Re: Vortex

Just a couple footnotes and helpful links while going into the new day. The satellite presentation says enough for is presently on a more west than west northwest course at this time. Amore southern track is apparently the way to go as the storm has headed more to the west over night.

The steering data (Which will update sometime during the next hour) would indicate that there is a High pressure steering flow due to the north of Felix. There is a secondary ridge in the eastern Gulf of Mexico. In between, there is a slight breakdown in the steering flow due to the ULL off of Miami. The overall effect of the ULL will be minimal, but will probably lead to a slow down in Felix's forward speed in about 12-16 hours...In fact, Felix may have slowed down by a Mile Per Hour in forward speed now...But that is tough to guage due to the satellite eclipse. The steering layer for a hurricane with pressures below 940mb is generally the 200-700mb level. I am attaching the link for that here: (It updates every 3 hours)

Yesterday's discussion from the NHC also featured an upcomming trough of low pressure. I am attaching a great link at the end of this paragraph in the event that you may want to follow it's evolution throughout the day. The trough is currentlyappraoching the Pacific coast and will likely turn Henrietta in the Pacific on amore northerly course. As far as interests go with far, I'm not sure that this will be much of a player. There is a solid ULL embedded in the trough, it is moving at a good clip, but it is sliding ENE ward now...Also, at this time, the trough does not seem to be a digging trough. I could speculate that the trough would have to be a "digging" troughin order to get enough influence going late in the period. Lot's can change as the pattern evolves and as the NHC has advertised with respect to this trough...As for now, it lookslike the overall affects will be slight. Link to Goes West Vapor Loop:
